Distribution of ferruginous pygmy owl Resident
|
The ferruginous pygmy owl (Glaucidium brasilianum) is a small owl that breeds in south-central Arizona and southern Texas in the United States, south through Mexico and Central America, to South America into Brazil, Bolivia, Paraguay and Argentina.
In Central America and South America, it is the most widely distributed pygmy owl and is probably one of the most numerous owl species in those areas. It is found in a wide range of semi-open wooded habitats.
